KEY MESSAGES
- Downward trend with temperatures through the weekend followed by another warm-up next week.
SHORT TERM /THROUGH THURSDAY NIGHT/
Issued at 1155 PM CST Wed Nov 11 2026
Seasonably cold mid-November weather is expected for Thursday with breezy northerly winds (15-25+ mph) and highs in the low to mid 40s for most areas. Isolated brief showers or occasional sprinkles are possible mainly Thursday morning into the early afternoon, and snowflakes could briefly mix in north of Highway 30. Forecast soundings show marginal saturation at the -10 C level, and with surface temps in the mid/upper 30s, rain is the most likely precip type from any showers that do develop. Moisture and forcing will be limited, so most of the area will not receive measurable precipitation. Heading into Thursday night, expect temperatures to drop back below freezing, bottoming out in the mid 20s to near 30 degrees.
LONG TERM /FRIDAY THROUGH WEDNESDAY/
Issued at 1155 PM CST Wed Nov 11 2026
Friday through Wednesday Assessment...a certainty of below normal temperatures through the weekend followed by another warm-up next week.
High pressure will remain across the Upper Midwest and Great Lakes through the weekend resulting in below normal temperatures for the area. Starting next week southerly flow across the Plains will result in another warm-up that will push temperatures above normal again into the mid/upper 50s.
While there will be weak disturbances aloft moving through the area, their passage will be marked by passing clouds.
AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
Issued at 1155 PM CST Wed Nov 11 2026
No significant changes to the forecast through Thursday. A deep upper trough will continue to dig into the Central to Eastern U.S. Locally for eastern Iowa and northwest Illinois, expect a reinforcing push of low-level cold air advection with surface winds gusting 15-25 kts from late tonight through Thursday afternoon. The northerly flow aloft will result in occasional rounds of low clouds moving through, with ceilings between 2500-5000 ft AGL. Therefore, brief periods of MVFR are possible. Isolated showers are possible near DBQ early Thursday AM, and temperatures could be cold enough for a brief rain/snow mix.
